The way it should be done

Excellent build quality; Great 4K screen; Touchpad and keyboard work well; Long battery life

Keys are too shallow; Boring design; No USB-A

Better suited for use on your desk rather than on the road, despite Dell's best intentions, but still a good laptop

Stylish; Sturdy; Extremely bright; high quality screen; Fast; Comparatively light and compact

Keyboard and battery life could be better

The Dell XPS 15 is one of the best laptops we have tested in a long time. It's hard to fault, as its weaknesses – such as the trackpad taking some getting used to and the chassis being prone to scratches – aren't too significant. The real caveat here, though, is the price.

Flawless performance; premium design; great keyboard

Price tag; chassis prone to scratches; not the most intuitive trackpad

Consider the bezel. That humble landing strip of plastic or metal that frames the screen in almost every high-tech device. Televisions have largely done away with the the wide bezels of old, at least in mid-price and better sets, extending the screen nearly all the way to the very edge for a...

The better configurations can cost a lot; while the keyboard could be bigger and the touchpad has a floaty feel

The DELL XPS 15 (6845sLV) is a high-end laptop that is a perfect replacement for desktop, and that's a funny place to be. It strikes a sweet spot between form and function, while still remaining functional for complex computing needs.

Attractive design; Strong performance; Great audio

Can run hot sometimes

The Dell XPS 15 is and remains a showpiece. When it comes to the notebook's case and input devices, Dell sets the bar high, but the main focus of attention here is the new 4K display.

High brightness; Good color representation out of the factory; Display calibrates very well; High resolution; High-quality case

Possible scaling problems; Heats up under load; Reflective display; Higher energy consumption compared to predecessor

The Dell XPS 15 is a fantastic laptop. Sure it has a premium price tag, but it also has premium features with a jaw-dropping 4K display, strong performance, and a well built portable design. One of the strongest selling points of this device is its versatility.

Gorgeous 4K display; Crisp; clear audio; Strong Performance

Expensive; Shallow key depth

As long as you stay near an AC outlet, Dell's sleek desktop replacement beats Apple's MacBook Pro for graphic artistry and office productivity. (Psst: And 1080p gaming, too.)

Speedy performance; Stellar 4K display

Lackluster battery life; Low-angle Webcam

Dell has been on a tear with its redesigns in 2018. On top of a daring overhaul on its flagship Ultrabook, the Dell XPS 13 , the Round Rock-based company has completely reinvented the Dell XPS 15 into a 2-in-1 laptop.

Impressive processing and graphical power on a single chip; Surprisingly tactile maglev keyboard; Ultra-thin design for a gaming-capable laptop

Radeon settings software needs a fix; Runs very loud during a heavy load; Little expensive

For the last couple of years, the Dell XPS 15 has been the standard-bearer for Windows 10 laptops. With powerful quad-core processors, dedicated graphics and a sub-£2,000 price, this is the machine that takes it to the top-end 15-inch MacBook Pros.

Stylish design; Great CPU and GPU performance; Good battery life; Excellent screen

A little heavy; Could do with another ThunderBolt port; Noisy fans
